Integrating It-Enabled Social Networks With Transaction Cost Economics And The Resource Based View Of The Firm, Ganesh D. Bhatt, Jatinder N. D. Gupta, Sushil K. Sharma
Journal of International Technology and Information Management
Prior research has mostly focused on transaction cost economics (TCE) to interpret the effect of information systems (IS) on organizational governance structures. A TCE based approach predicts that information technology (IT) will lead to increased use of electronic markets to coordinate economic transactions from electronic hierarchies. However, there is contradictory evidence in the literature regarding the rise and importance of cooperative relationships, joint ventures, and value-added partnerships integrated through information systems. To reconcile these contradictions, this paper analyzes the effect of IT on governance structures based on the TCE, social network theory, and the resource based view (RBV) of the …

Internet Entrepreneurship And Economic Growth, Gerald V. Post, John F. Pfaff
Internet Entrepreneurship And Economic Growth, Gerald V. Post, John F. Pfaff
Journal of International Technology and Information Management
This paper looks at national attempts to promote economic growth through the Internet. Growth can be driven through service exports or internally through increased service transactions and fostering entrepreneurship. India is often held as an example of service exports, but economic statistics show that India might not be a good example for other nations because net service trade is negative and wages have been economically distorted. Ultimately, developing nations need to find internal growth models. Internal growth could be driven though increased consumption due to improved information, or increased investment expenditures from infrastructure investments.

Information View Of Organization, Bob Travica
Information View Of Organization, Bob Travica
Journal of International Technology and Information Management
This article proposes an information view of organization that brings the information systems field closer to organization theory. Although voluminous bodies of literature have been developed within each of these disciplines and links between them do exist, their mutual informing is still insufficient. The proposed view of organization is intended to help convey results of information systems research to organizational scholars, while broadening theoretical horizons of the former. This article discusses the premises, conceptual framework, examples, and preliminary evidence of the information view of organization.

Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr
Deciding On The Appropriateness Of B2b Reverse Auction Technology Adoption: An Ahp Approach Combined With Integer Programming, Tobias Schoenherr
Journal of International Technology and Information Management
Although Business-to-Business online reverse auctions have emerged as a promising purchasing tool, no research has been found that provides a model to assess the reverse auction decision in a systematic way. This paper fills this gap by presenting an integrated approach, utilizing Analytic Hierarchy Process techniques and an Integer Programming Formulation, to decide whether Reverse Auction Technology (RAT) adoption is cost-effective and appropriate. The model developed is a practical decision support tool that allows for the consideration of both qualitative and quantitative decision factors, and for the adoption of multiple modes of RATs, which are contrasted to traditional purchasing.
The Ecology Of Interorganizational Information Sharing, Jane Fedorowicz, Janis L. Gogan, Amy W. Ray
The Ecology Of Interorganizational Information Sharing, Jane Fedorowicz, Janis L. Gogan, Amy W. Ray
Journal of International Technology and Information Management
Increasingly, companies use interorganizational information systems to support business process partnerships, such as automatic replenishment systems and other supply chain initiatives, invoicing and payments, and insurance claims processing. Inter-firm networking in turn can increase the visibility of information generated and used by business partners. These business partners may experience intended and unintended impacts from the changes in the partnering relationship, in effect altering the ecology of the organization. Yet IT researchers rarely study an organization’s ecology, focusing instead on impacts upon internal processes. Our goal in this paper is to propose a definition of interorganizational information ecology, to provide IT …

Creep-Fatigue Life Prediction - A Ductility Model, Tarun Goswami
Creep-Fatigue Life Prediction - A Ductility Model, Tarun Goswami
Biomedical, Industrial & Human Factors Engineering Faculty Publications
Creep-fatigue life prediction methods are briefly reviewed. Phenomenological methods of life prediction are very popular, since they use several test and metallographic parameters in model formulation. They also require numerous test parameters determined from specialized tests. Requirements of phenomenological methods have been summarized. Ductility measurement and modeling aspects have been reviewed. A new model has been developed with the assumption that with increasing fatigue cycles the ductility gradually decreases and the specimen fails as a result of exhaustion of ductility. This has been achieved in terms of dynamic viscosity (product of stress and cycle time), equated with material toughness, which …
